Halifax entered a relatively short-lived marriage with Stanislav Grof in 1972.[1] While together the two examined the use of LSD as a support mechanism for those dying, jointly publishing the book The Human Encounter With Death in 1977. The book discusses several "rebirth" incidents which are rather similar to regular reports of near death experiences.[4]

In 1979, Halifax founded the Ojai Foundation, an educational and interfaith center. In 1990 Halifax founded Upaya Zen Center located in Santa Fe, New Mexico. The center offers Zen training, in addition to various courses and retreats on topics such as engaged Buddhism and caring for the dying.[5] According to author Sarah Buie, Upaya is, "...a residential and teaching center on the outskirts of Santa Fe on the site of earlier Buddhist communities. While proceeding in an organic and incremental way, integrating existing structures into the Upaya campus, Joan's vision for its present form has been comprehensive. It is based on her deep understanding of the consonance of mind and spatial expressions. She considers our condition of interrelatedness and interdependence (ties to ancestors and traditional uses of the land, natural cycles and resources, placing sites within the local topography of mountain and river, the interdependence of exterior and interior spaces, and relationships with the community itself) in the design choices she has made. Caring stewardship of the land and its resources has been a constant factor in the development of the site.[6]

As has already been noted, Joan Halifax has done extensive work with the dying over her career. Professor Christopher S. Queen writes—in the book Westward Dharma (edited by Charles S. Prebish and Martin Baumann), "She teaches the techniques of 'being with death and dying' to a class of terminally ill patients, doctors, nurses, lovers, family, and friends. She speaks calmly, with authority. In a culture where death is an enemy to be ignored, denied, and hidden away, Joan physically touches the dying. She holds them, listens to them, comforts them, calms them, and eases their suffering by any means possible. She shares their thoughts and fears; she feels their last shuddering breaths, holding them in her arms. She travels easily from church to synagogue, hospice to hospital, dispensing techniques and training born of Buddhist traditions and beliefs in a culturally and spiritually flexible manner."[7]
